Little messy and bad camera quality, but here is my updated setup from last year.
Desk is a little spaghetti wired right now. Been playing a lot of Saturn and PS2 lately so I have them on top of the desk and kind of made a mess of my Switch games I keep on the desk.
Shelves on the left I keep my PS1, PC Engine, Neo Geo CD and Dreamcast games. On the Right my GB, DS, 3DS, NES, Wii, GC, Wii U, N64.
Last time there was a bunch of random collectable boxes and stuff here, but I cleared that out and bought some dvd shelves and went hard into PS2 collecting. So here is my PS2, JP PS2, JP PS1 and Xbox stuff with my NES and SNES manuals on top.
Middle shelf is 360, PS3, 3DO, Lynx, 2600, 2700, Intellivision, SNES, PC and GamePro, EGM magazines.
NES boxes with manuals, SNES Boxes with manuals. The NES and SNES boxes on the PS2 shelf are for the ones I don't have boxes for. Also some system boxes.
Genesis, Master System and 32x.
Saturn, Sega CD, JP Saturn and Mega CD games.
